Gentlemen,
    I am reaching the point of purchasing an engine and trying to  
make a few decisions on what I want/need. What I have is a single  
seat biplane, what I need is 200/220 hp. Maximum airframe speed is  
180 mph. I would like to use a n/a Renesis engine, p-ported if  
needed, turning at 6000 rpm using the 2.85 PSRU. I like the 6000 rpm  
as it is easy on the engine. I like the 2.85 because the prop turns  
in the "correct" direction. Using the slower turning "monster" prop  
as has been discussed here appeals to me especially if it increases  
climb rate. Is this HP realistic with this setup?  If this setup is  
not the best for what I need then what is? I am not an "engine man"  
so my decisions will be based on the experience of others.
Thank you for your advice,
Randy
